GOAL-P.Usiniv'ef.DEVICE Y To all whom t may concern Be it `known that I, JAMES M. JOHNSON, a citizen of the United States, residing at Mobile, in the countyof Mobile and State of Alabama, have invented'. certain new rand useful Improvements in Coal-Pushing Devices, of which the following is'a specification. Y

The present invention relates to a new and improved coal pushing or feeding device adapted to be used on locomotive tenders or coal cars, or in connection-With other means anddevices adapted to contain coal in bulk. The principal object of my'invention .is to providea coal-pushing or feeding device primarily designed for use in lconnection with locomotive tenders which is1 adapted to push or feed'the coal towardthe normally open end of the tender thus facilitating the firing of the engine, or locomotive. f V'Another object of the invention :is to provide a-device of the above character which includes means normally positionedl behind the bulk of coal together vvith.` means and mechanism to move .the same longitudinally whereby the coal Within the tender may be moved toward the iorvvard end thereof so that the fireman may have access thereto at all times.

f Still another Object of the invention is to provide, in conjunctionV WithA the means abover referred to, 'other' means adapted to normallyV assume a horizontal position and receive part ofthe bulk of coal carried by the tender, together with automatic `.mechanism to tilt Vsaid additional means at certain times whereby the/bulk of coal carriedthereby will be fedv into the'main containerportion of the tender. l f v Al further object of the invention'is to provide suitable antifriction means to facilitate the operation of the moving parts of' the deviceand the tilting offcertan parts thereof as will beV hereinafter fully described.

A still further object of the invention is to provide .a device ofthe above character which is of such construction 'whereby it 'can be used in'connec'tion with locomotive tenders of conventional construction and Wherein 'its' application thereto will notnecessitate the changing of the normal construction to any'appreci'able extent.-

durable, `and which'jit isrb'elieved maybe manufactured at `a reasonably loW cost.

f Still another object ofthe invention is to provide a coal pusher-'or feeding device which may be controlled from the cab 0f the locomotive. v ,l Various other objects andadvantages of my invention Awill become apparent during the continuance of the following description.

In lthe drawings Fignre l is a vievv intop plan showing my invention asin itspreferred embodiment.

Figure 2 isa view in side elevation. Figure 3 is a view in longitudinal cross section taken `on line 3-3 of Figure 1, the

pushing device being shownin full Aline in its normal position "and'in dotted lines in an extended position. 'A

w. n n n i A glfiguret isa view 11i transverse cross section taken: on linell-f of Figure 1Q L 'In 'describing my .invention in detailV 10 designates in fits-entirety, a conventionalV forni of locomotiver tender Awhich is provided with ,the usual Water compartments 11 and l2 'to which' access ymaybe had through an intake opening" 1'3'7that is normal-'ly `closed bya cover' 14 andthe main coal containing space 15. Ad'acent the forward end ofthetender,"the' Si es formed by the Water coinpartmentylQ carry across piece lrfrom -which depends vthev convenf tional gate4 17 that hasan opening 18 located in thel lower-'end thereofv through which coalmay be shovell'ed. The longitudinal edges" of the .tender are extended above the upper end of the vvvater`compart-- ment 12 as at 19 so as to form an additionalspace 4for receivingcoal and slightly in advance of the intake openingv 413, therwater compartment 1l carries an` up'standing cross member 20 Which serves tov'mark the rear end `ofthe coal containing space. It

willV be noted that when the'tender filled,

with coal the bulk lofcoal not only occupies the mainI space or'compartment 1'5l but also lies on the upper endofthewater vcompartment`s12 and the upperjsurfaceof the water compartment .11' i'nvadvanceV of thefciosvs ."'In equipping the" tender vvith the device of my invention, I rst provide a steam ioo cylinder 21.V Which is arranged in the plane of the central longitudinal axis ofthe tenderl and 'soas to project artly within the water chamber h'111' as :clear y shown in Fig- Y compartment 11 as will be noted upon reference to Figure 1, but themain part thereof lies within the water compartment. The

steam cylinder carries a piston' 22 having a head 23V for operative movement'therein and the vpiston projects'through an opening 24 into .the main coal compartment 15;;as also shown in Figure 3.

-Within the water compartment 11 are arranged longitudinal sleeves 25 and 26' through which extend steam pipes 27 and 28- which connect to opposite ends of the steam cylinder 21 `as clearly shown in Figure 3. The steam pipes 27 and 28 extend downwardly on the outside of the water compartment and are carried on the under side of thetender 'by means of brackets 29. The steam pipes are also-connected to other steam pipes 30 and'314 that are carried by the locomotive `and which are provided with suitable valves (not shown) whereby ingress of steam into the cylinder 21 may be controlled. n

On its outer `end andV within Ythe main coal compartment 15, the piston 22 carries the main pushin memberl 32 which is of slightlyless widt than the main coal containing s pace 15 and which carries at its lower end a gate 33 that is hingedlfthereto asiat 34 for folding movement` inl one direction. In lother words during theforward movement of member 32, the ate will l be firmly held in alignment therewlth butv upon return movement, the gate will 'fold forwardly upon' contact with any loose coal or.. foreign matter in the bottom 'of the coal `containing space 15.l The front face of the member 32 may also be provided with reinforcing members 35 which are secured in place as at 36 land which may be arranged in angular relation with respect to each other as shown in Figure 4. The referred position `of the reinforcing mem ers `is in substantially inverted U shape relation,"the Vupper ends thereof coming to gether at a point preferably in alignment withtherpiston 22 and the lower ends thereof terminating adjacent the outer, lower edge =of the member 32; r

@At its upper `end the member 32 is providedV with Qa Aseries of. spaced sleeves 37 through which is arrangedy a pintle 38'which carries `Vrollers 39 on its outer ends for engagement vwith A tracks 40 carried on the inner-facesof the Water compartment 12jas clearly Y shown `in Figures 1 and 4.v lIn addition to aiding in the support of the memher 32, the pintle 38 and4 the rollers carried therelnyA together with' the` track 40` serve to facilitate-movement of the: member 32 and preventgsagging thereof.

flrf-Qn'jthat portion on the top'of the water cemrmrillrwrlty ll-z'in` advance 4ofthe 9.1955

member 20, I arrange a supplemental pushing or carrying member 41whose top edge is provided with .a Ydepending extensionv 42 s that enters the main coal space 15 andwhich isinturn provided with spaced sleeves 43 which receive the pintle 38, above 'referred to, and serve to maintain the supplemental pushing vor carrying member 41 in yhinged relation tothe member 32.

At its rear end the supplemental Vmember 41 is turned upwardly as at 44 and then out- 'wardly as at 45 toV project overvthe cross member 20 whenthe device is in itsnormal position and as clearly shown in'Figure 3. The sides of the supplemental member are turned upwardly' as at 46 and then outwardly as at 47 to project over the upstanding portions 19 of the tender and again bent downwardly to terminate in longitudinal sleeves 48. Between the Vportion 47 of the supplemental member .41 andthe upper edges ofthe extended portions 19 of the tenvmatically tiltthesupplemental member 41 after the'same has-been moved forward a certain distance, I provide the longitudinal sleeves 48 vthereof with longitudinally disposed rods 52 which carry at their forwardl ends downwardly and Aforwardly' extending trip arms 53 as clearly fshown in Figures2 and 3. At suitable points on the sides ofthe tender 10 are arranged stop rollers 54 with which the trip arms Y53 become engaged after the supplemental member 41has beenmoved forward av 'certain distance. When the trip arms engage the stop vrollers 54 and the member 32 continuesto carryifthe supple mental member forward, theY angular disposition of the trip arms causes the supplementalmember to betitled until it finally reachesA the position shownin, dotted lines` in Figure-3. Itfwill-befobserved that the coal contained on the supplemental member .will be .dumped intothe main coal-compartment 15 so that the entire bulk ofjcoal carriedby the. tendervwill have been placed'- before the opening-118 'inTA the outletg'ate 17.' '.-On reference to 'Figure ,1 it will bernoted that'the intermediate portion ofthe supple#l mentalmember 41 is suitably curved as at 55 to conform to the contoury of the upper` part of the steam cylinder 21'.A n

lIn operation the-coal is depositedin the main .receiving space 15 and upon the sup-V plemental member 11 in the conventional way. As the fireman shovels the coal away from the opening 18, hemay manipulate suitable valves in the locomotive cab.so as to cause steam. to be admitted to the rear end of the steam cylinder 21 which will force the piston 22 forwardly and carry with it the main pushing member 32 and the supplemental member 11. During the rst few feet of movement of the piston, the main pushing force will be exerted by the member 32 and the supplemental mem bei' will be carried forward in a horizontal position. However', continued forward movement will bring the trip arms into engagement with the stop rollers 54 so as to tilt the supplemental member 41 in the position shown in dotted line in Figure 3. Thus it will be observed that the entire bulk of coalmay be positioned immediately adjacent the opening 18 in the gate 17 from which point it may be easily and quickly removed by the fireman.

From the foregoingit is believed that the advantages and novel features of my invention will be readily understood and therefore further detailed description is deemed unnecessary.
